UNITED. STATES PATENT OFFICE BOLLO F. WALTES, OF DETROIT, MICHIGAN, ASSIGNOR TO UNITED-CARR FASTENER CORPORATION, OF CAMBRIDGE, MASSACHUSETTS, A CORPORATION OF MASSACHU- SETTS SNAP FASTENER REISSUED Original application filed July 24, 1924, Serial No. 727,958, and in Canada November 9, 1926. Divided and this application filed January 21, 1929. Serial No. 333,908.

This invention aims to provide an improved detachable snap fastener particularly useful in connection with upholstery installations.

This application is a division of my prior application Serial No. 727,958, filed July 24, 1924. V

In the drawings, which illustrate a preferred and two modified forms of my invention:

Figure 1 is an elevation view of the inside of an automobile door, showing the shiftable studs positioned upon the frame of the door;

Fig. 2 is an inside elevation of the upholstery installation;

Fig. .3 is 'a longitudinal section through a portion of the door showing one of the studs with the upholstered installation secured thereto;

Fig. 4 is a rear elevation of the preferred form of removable stud;

Fig. 5 is a front elevation of a preferred Fig. 6 is a section similar to Fig. 3, showing a modified .form of stud secured to the door frame;

Fig. 7 is a rear elevation of the modified form of removable stud shown in Fig. 6;

Fig. 8 is a section similar to that shown in Fig. 6, showing a second modified form of removable stud; and

Fig. 9 is a rear elevation of that form of removable stud shown in Fig. 8.

Referring to the preferred form of my invention, as illustrated in Figs. 1 through 5, I have shown (Fig. 1) an automobile door 1 having a frame part 2, to which are secured a plurality of socket-engaging studs. Beneath each stud, I have provided in the frame part 2, an aperture 2 which in this instance serves as a guide in positioning the studs on the frame 2, so that they will be in the proper position for engagement with eyelets on the upholstered part.

These apertures 2 may also be used for stud-receiving apertures when the upholstered part is provided with stud members. Thus the apertures 2 may be used for either of the purposes mentioned above, but I prefer in this invention to use them as markers for positioning the studs on the frame part 2.

Each stud is pressed from a single sheet of metal (Figs. 4 and 5) and presents a contractible and expansible head 3, a base 4 and an underlying spring finger or shank 5 formed from the base 4, thereby to cooperate with the base to provide a clip-like portion. When secured to the frame part 2 of the door, the base of the stud lies against the front web 6 of the frame part 2 and the spring finger 5 slips over the edge of the frame part and bears against the under side of the web 6, thus permitting the stud to be shifted transversely relative to the frame part 2, while the stud may be held in the desired position by the spring finger 5, as best illustrated in Fig. 3.

The heads of the studs have slots 3*, which extend from the head of each stud a substantial distance into the raised portion 4? (Fig. 3) of the base 4 of the stud to permit bending of the contractible and expansible parts of the stud upon straight lines, between the slots, which do not intersect the head of the stud, as illustrated in Fig. 5. Thus the raised portion 4 of the stud permits the head of the stud to contract and expand without interfering with the web 6 of the frame 2 of the door.

The upholstered part for covering that side of the door at which the studs are secured, comprises a backing 7 of substantially rigid material, such as cardboard or the like, a plurality of sockets or eyelets 8 and a flexible covering 9 of fabric, leather or the like at one side of the backing 7.

Each eyelet 8 presents a stud-receiving aperture 10 and a rivet part 11, which extends through an aperture 12 in the backing 7 'and is clenched over a clench washer 13 at the opposite side of the backing, as best illustrated in Fig. 4. The rivet part of the eyelet flares outwardly back of the studreceiving aperture, thereby to provide a recess into which the head of the stud fits. when a stud is engaged with the eyelet.

When the eyelets 8 are all secured to the backing 7, a padding 14 is placed over the surface of the backing at that side thereof frame at which the clench washers are exposed. Then the flexible covering 9 is stretched over the padding 14: and secured to the opposite side of the backing in any suitable manner. Thus the upholstered part is provided with a neat and finished covering, which conceals all the parts of the fasteners when the upholstered part is secured to the frame. The upholstered part may be secured to the frame of the door by placing it against the studs and pressing the sockets or eyelets 8 into engagement therewith, thus drawing the edges of the upholstered part against the frame to rovide a smoothly fitting edge which fits tig tly against the surface of the {Frame part 2 of the door 1, as illustrated in f for any reason any of the sockets do not register wit-h the studs when the upholstered art is being secured to the door, the studs may be shifted transversely relative to the frame until they do register with the eyelets 8 which are then pressed into engagement therewith. Thus the upholstere part may be fitted to the door, by shifting the studs until the edges of the upldiolstelred part align with the edges of the oor Referring now to Figs. 6 and 7 ,'I have shown a modified form ofstud for use in upholstery installations.

This studis substantially as shown and described in connection with the preferred form ofmy invention, except that it is provided with a detent 15 which is pressed from the sprin 2" in the ront web 6 .of the frame part 2 of the door, as illustrated inFig. 6. The detent 15 is. preferably cone-shaped, so as to provides cam-shaped surface 16 for disengagin the stud from the aperture 2 b movin t e stud in any transverse di-' rectlon relative to the'pframe'part 2. The- Lcross-sectionof the detentis substantially. smaller than the cross-section of the "'ape'r-..

ture 2", as illustrated'inIFig; 3, therebyto ermit transverse shifting of the stud for gnment with its cooperating eyeletv 8 in the upholstered part. v

Re erring now to the modified form of stud, as illustrated in Figs. 8' and 9, I have shown a stud substantially as shown and described in connection with the modified form of my invention shown in Figs. 6 and 7.

In this instance, however, the detent 17, for engagement with the aperture 2 in the part 2, is so formed as to present a straight wall 18 at that side thereof toward the inner edge'of the frame part 2, thereby to provide a stop to prevent disengagement of the stud from the frame by a ull at that finger 5 and engages the aperture until the detent is free from the aperture 2. Then the stud may be removed from the frame.

While I have shown and described preferred and modified forms of embodiments of my invention, it will be understood that changes involvingomission, substitution, alteration and reversal of parts, and even changes in the mode of operation, may be made without departing from the scope of my invention, which is best defined in the following claims.

Claims:

1. A one-piece snap fastener member formed entirely from sheet metal and having a U-shaped portion comprising a base, a hollow boss pressed fromsaid base adjacent to the free ,end thereof to provide a stud head and neck for cooperative engagement with a snap fastener socket, a portion normally paralleling said base portion and yieldably connected thereto to cooperate therewith for attaching the snap fastener member to a support and a projection pressed from said last mentioned portion and extending toward the base to provide a detent for engagement in a hole in a sup port to which the snap fastener member may be secured thereby to prevent the snap fastener member from being accidentall displaced from a predetermined position re ative to the support.

2. A one-piece sna fastener member formed entirely from s set metal and having a U-shaped portion comprising a base, a hollow boss pressed from said base adjacent to the free end thereof to provide a stud head and neck for cooperative engagement with a snap fastener socket, a portion normally paralleling said base portion and yieldably connected thereto to cooperate therewith for attaching the snap fastener member to a support and a projection pressed from said last mentioned portion and? extending toward the base to provide a i detent'for engagement with a hole in a support to which the snap fastener member may e secured thereby to prevent the sna fastener member from being accidental y displaced from a predetermined position relative to the support, and said projection havinga sloping surface facing toward the open end of said U-shaped portion to act as a wedge to spread the sides of the U-shaped portion apart when forced over the edge of the support.

In testimony whereof, I have signed my name to this specification.
